JUnit testing of DelegatingActionProxy using MockStrutsTestCase

Hi
I am trying to use MockStrutsTestCase to test my application that uses DelegatingActionProxy ( struts + spring action delegation). The classic method (for pure struts action testing...i.e providing the setRequestPathInfo, requestParameters and actionPerform() ..) doesn't seem to work for this case and the alternatives I've found on the web so far are either too unfamiliar or do not work...

Can anyone suggest how can I go about this ?

Thanks
